Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic waterproof wire harnesses, and in particular to a pre-installed split type fixing piece of a photovoltaic wire harness. Background Art

[0002] Cable ties are also called strips. As the name suggests, they are straps for tying things. They are designed with a stop function, so they can only be tied tighter. There are also detachable cable ties.

[0003] There are many types of cable ties. For example, the wiring equipment industry is divided into: self-locking cable ties, label cable ties, snap-on cable ties, anti-tamper (lead seal) cable ties, fixed head cable ties, label cable ties, pin cable ties, aircraft head cable ties, bead hole cable ties, fishbone cable ties, weather-resistant cable ties, etc.

[0004] When bundling photovoltaic wire harnesses, existing cable ties cannot fix the wire harnesses on the mounting surface alone. Multiple holes need to be punched, and the cable ties are punched and the wire harnesses are fixed on the mounting surface. This wiring harness positioning method is cumbersome and cannot adapt to mounting surfaces in different situations.

[0005] To this end, we propose a pre-assembled split fixing for a photovoltaic wiring harness. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a pre-installed split fixing for a photovoltaic wiring harness. By providing a strip guide and an edge clip, the wiring harness can be adapted to different mounting surfaces. When encountering a thin mounting piece, the edge clip and bolts are used to fix the wiring harness. When encountering a mounting surface such as a wall that cannot be clipped, bolt fixing is used. At the same time, a support plate is supported on the bottom of the strip guide, which can further provide support force to it and reduce the damage life of parts.

[0008] (II) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A pre-installed split fixing for a photovoltaic wiring harness includes a strip, and is characterized in that it also includes a strip guide and an edge clip, the strip extends along a track within the strip guide and is wrapped around the outside of the wiring harness, and the edge clip cooperates with a bolt thread pre-installed in the strip guide.

[0011] Preferably, one end of the strip has a locking head, and the other end is a free end that can extend into the locking head and be adjustably locked with the locking head.

[0012] Preferably, both ends of the strip guide are provided with arc-shaped interfaces for extending the strip, and the arc-shaped interface at one end of the strip guide also extends outwardly with a strip through groove, and the strip can move freely up and down in the strip through groove.

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See attached Figure 1-2 A pre-installed split fixing for a photovoltaic wiring harness includes a strip 1, characterized in that it also includes a strip guide 2 and an edge clip 3, the strip 1 extends along a track inside the strip guide 2 and is wrapped around the outside of the wiring harness, and the edge clip cooperates with a bolt thread pre-installed in the strip guide 2.

[0028] One end of the strip 1 has a locking head, and the other end is a free end that can extend into the locking head and be adjustably locked with the locking head. The two ends of the strip 1 are wrapped around the outside of the wire harness to tighten the wire harness and prevent it from loosening.

[0029] Both ends of the strip guide 2 are provided with an arc-shaped interface 2.1 for the strip to extend. The arc-shaped interface 2.1 at one end of the strip guide 2 also extends outward with a strip slot 2.2. The strip 1 can move freely up and down in the strip slot 2.2. During use, the pre-bundled wire harness can be first placed on the strip slot 2.2, and then the strip 1 is used to pass through the arc-shaped interfaces 2.1 at both ends from front to back to form a bundle of the wire harness placed in the strip slot 2.2.

[0030] Furthermore, in some embodiments, in order to prevent the locking head of the strip 1 from extending into the arc interface 2.1 and getting stuck inside, the entrance size of the arc interface 2.1 is smaller than the size of the locking head of the strip 1. This design allows only one hand to pull the free end extending from an arc interface 2.1 and wrap it around the outside of the wiring harness, and then pass it through the locking piece stuck on the outside of another arc interface 2.1, thereby reducing the user's operating difficulty, increasing ease of use, and improving work efficiency.

[0031] The strip guide 2 is provided with a receiving groove for receiving the head of the bolt therein to avoid affecting the normal bundling use of the strip.

[0032] The front end of the edge fastener 3 is in the shape of a hook and can be hooked on a thin mounting member. Figure 2After the edge clip 3 is hung on the thin mounting part, the bolt pre-installed in the strip guide 2 is screwed close to and against the surface of the thin mounting part. The edge clip cooperates with the bolt to fix the strip guide 2 to the thin mounting part, and the process of punching holes (mounting holes) can be omitted to reduce the risk of reduced structural strength. This installation method can be freely selected to be installed in a suitable position, which is convenient for movement.

[0033] In some embodiments, in order to improve the support for the strip guide 2, a pair of support plates 4 are hinged on the back of the strip guide 2, and a hook structure is formed at the end of each support plate 4, and a pair of slots compatible with the hook structure are provided on the edge clip 3. By shortening the distance between the edge clip 3 and the strip guide 2, the support plate 4 is prevented from falling off the slot and damaging the support structure.

[0034] It is understandable that the length of the hook at the head end of the edge clip 3 is set to a degree that does not interfere with the advancement of the bolt, thereby avoiding assembly collision between the two during installation.

[0035] When the mounting surface is such that the edge fastener 3 cannot be hooked, the edge fastener 3 can be removed from the bolt and assembled only by the bolt and the reserved hole of the mounting surface; or the edge fastener 3 can be turned over and assembled with the bolt, which can adapt to mounting surfaces in different situations.
